LAUDA mobile ultra-low temperature freezer Mobifreeze M 270
The LAUDA Mobifreeze M 270 mobile ultra-low temperature freezer is an innovative solution for safe deep-freeze transportation at constant temperatures, particularly in the pharmaceutical, biotech and chemical industries. This battery-powered ultra-low temperature freezer is ideal for safely transporting laboratory samples, temperature-sensitive reagents or highly sensitive materials. Precise temperature control and robust construction offer a decisive advantage over older or insufficiently insulated models. Similar to the reliable KIRSCH LABO-125, this device uses a powerful refrigeration system that guarantees the user stability and safety.
Functionality and special features
This mobile unit combines an energy-saving refrigeration system with a lithium iron phosphate battery to provide several hours of stable operation even without a mains connection. The high efficiency of the cooling capacity is particularly noteworthy: for example, the unit can cool down from 20 °C to -80 °C in just three hours, which minimizes time-consuming waiting times. During transportation, the system only loses temperature slowly thanks to the advanced insulation and ensures stability even in less ideal environments.
Those who require constant temperatures in professional cold chains - for example for clinical studies, vaccines or bioreagents - benefit from the following technical highlights:
- Working temperatures from -86 °C to -50 °C
- Fast cooling time from 20 °C to -80 °C in around three hours
- Durable and maintenance-free high-performance compressors
- Robust lithium iron phosphate battery technology for uninterrupted operation
- Usable space of 270 liters with additional insulating cover plates
- Tested temperature stability of ±3 K
In addition, the interior is made entirely of stainless steel and has a 13 mm internal diameter feed-through for inserting external control sensors. The temperature display with touch function and alarm option is also buffered by the rechargeable battery, which ensures maximum operational reliability. This means that sensitive samples, vaccines and chemicals can be transported safely even in the event of logistical bottlenecks. In contrast to the JULABO CF41 refrigerated thermostat, which is primarily designed for constant process conditions in laboratory reactor systems, this mobile deep-freeze solution was primarily developed for applications that require maximum temperature precision even when on the move.
Certification with common standards such as CE underpins its suitability for professional use. Added to this is the low energy consumption of around 9.2 kWh per day, an important aspect for companies that place increased value on sustainability as well as functionality.
Application examples
- Transport of highly sensitive laboratory samples, such as DNA- or RNA-based substances, across multiple locations.
- Maintaining safe refrigeration for biopharmaceuticals and vaccines during short or multi-hour road transportation.
- Ensuring a constant ultra-low temperature environment during in-plant transfer of temperature-sensitive raw materials in the chemical industry
- Optimal storage and safe transfer of proteins or enzymes in research laboratories that rely on extremely low temperatures.
FAQs
How long does the ultra-low temperature last during transportation without a mains connection?
The battery is designed to last up to four hours without external power while maintaining a constant temperature thanks to efficient insulation.
Is operation possible even if the power supply fails?
Yes, thanks to battery buffering, both the display and alarm functions remain active so that temperature monitoring is permanently guaranteed.
Which refrigerants are used
Environmentally friendly refrigerants are used: R-290 and R-170, both of which are characterized by a very low global warming potential (GWP) and are therefore a sustainable alternative to conventional refrigerants.
What role does the feed-through opening inside the appliance play?
This opening (13 mm internal diameter) allows external sensors to be inserted, for example for additional temperature monitoring or documentation during transportation.
Are the controls easy to use?
The 4.3" touchscreen control panel is clearly laid out. All relevant parameters can be set quickly in the menu and the digital displays provide current measured values in real time.
Conclusion
This mobile ultra-low temperature freezer offers a unique mix of high cooling capacity, battery operation and ease of maintenance. Thanks to fast cooling times, efficient thermal insulation and modern sensor technology, it is the ideal choice for the safe transportation and storage of temperature-sensitive products. With its CE marking, low-emission refrigerants and robust stainless steel interior, it combines safety, environmental compatibility and user-friendliness, ensuring a reliable cold chain at all times.
